Is it cool?

Nova, as much as I hate to rain on your parade, with the exact specs he quotes, assuming 100ms opening (slow because it's a PVC BV), the 72" barrel, and a 200 gram projectile with a drag coefficient of 0.5, GGDT predicts exactly 800 feet.Almost uncanny, isn't it?

At an operating pressure of 60psi with your 6' barrel, a D cell as ammo i would predict *looks into Crystal ball* a distance of around 400', that is being generous.Please don't think that i am trying to erk you mate, i just don't like when numbers get thrown around- i have a hard enough time trying to understand them as they are.

Edit- DYI, i like rain, i guess the only thing for spudchucker to do is test the distance achieved, with either a tape measure or a walker wheel.

America, the greatest gangster of all time. With 200 million odd foot soldiers at it's whim and call.
When you fill your car with refined oil remember that it has been paid for with blood and guts, some from your own countrymen, most not.

I know when i tried to download GGDT only certain links worked, try having a look for a different link.
